SAN DIEGO, San Diego County, Calif., Oct. 16, 2026 — A sedan and a semi-truck collided early Thursday morning, October 15, on southbound I-805 just north of Adams Avenue in San Diego, according to the California Highway Patrol. At least one injury was reported at the scene.
The crash was reported shortly before 2 a.m. Responding units initially described it as a traffic collision with unknown injuries before the call was upgraded to reflect at least one person hurt.
Radio traffic indicated the sedan suffered major front-end damage and that smoke was coming from its engine after the impact, CHP logs show. The collision blocked multiple lanes of southbound I-805, with units reporting all lanes stopped for a time before officers began reopening them to clear traffic.
A tow was requested to remove the big rig from the roadway, and the CHP said crews worked to restore the right lanes through the early morning hours. The extent of injuries and what led to the collision have not been released. The CHP's investigation into the crash is ongoing.
We wish those injured a full recovery.

Frequently Asked Questions
Does driver fatigue play a role in truck crashes?
It can. Fatigue slows reaction time and is a factor investigators usually examine in early morning or overnight collisions involving commercial trucks, though a cause has not been confirmed in this case.
What should I do after a crash involving a commercial truck?
Call 911, move to safety if possible, and seek medical evaluation even if injuries seem minor. Get the names of any agencies that respond and note the truck company or markings if visible.
Why do trucks need more distance to stop than cars?
Loaded commercial trucks weigh far more than passenger vehicles and require longer stopping distances, especially at highway speeds, which is why following distance and speed matter so much in mixed traffic.
What makes truck crashes different from typical car accidents?
The size and weight difference between a semi-truck and a passenger vehicle usually means more severe damage and injury to occupants of the smaller vehicle, as reflected in the front-end damage described in this incident.
What to Do After a Truck Crash in San Diego, CA
If you're involved in a crash with a semi-truck in San Diego, prioritize safety first: turn on hazard lights, move away from traffic lanes if you're able, and wait for help. Even if you feel fine, get checked by a medical professional soon after, since some injuries, especially from sudden impact, don't show symptoms right away. Request a copy of the official collision report once it's available, and keep records of any medical visits or vehicle damage. Giving yourself time to process the event and lean on family or local support resources can also make a real difference in the days that follow.
